Storyboard Scroll Direction Set the direction that storyboard content will move when scrolling.

Canvas Controllers

Name                                 Description
Auto-Add Hooks On Scene Save When saving a Canvas Controller scene, Canvas Flow can automatically add storyboard hooks to the appropriate game objects. This will allow the objects to be hookable in the storyboard editor window. You may want to disable this if you are not working with storyboards.
Canvas Scaler Reference Resolution Set the Canvas Scaler component's default reference resolution for new canvas controllers. This should be set to the resolution at which you are designing your UI. In addition to the Canvas Scaler, this will affect the proportions of the canvas controller in the storyboard editor.

Canvas Controller Play-Mode Adjustments

It can be useful to run a canvas controller scene directly in the editor to preview changes quickly. Canvas Flow will make the following temporary adjustments when you enter play-mode from a canvas controller scene directly to make this process simpler. Note that these adjustments are only applied in the editor when entering play-mode from a canvas controller scene directly and are discarded once play-mode is exited.

Name                                 Description
Camera Clear Flags Enable this to set the canvas controller's Camera Clear Flags to 'SolidColor' when running the scene directly in the editor. By default, canvas controllers have their clear flags set to 'Depth'. This allows them to be transparent over your game's content. However, when running directly in the editor, your game's main camera will not be present to clear the screen.
Create EventSystem (If Necessary) Enable this to create an EventSystem (if one doesn't exist) when running the scene directly in the editor. By default, canvas controllers have no EventSystem, expecting one to be present elsewhere in your game. However, when running directly in the editor, your main EventSystem will not be present to accept input events.
